Fuhua: Undercurrent

A volume of military secrets that have been sealed for seven years, a conspiracy spanning three continents, and an ultimate exploration of the nature of "intimacy." The story begins when Sherlock receives an encrypted message from his brother Mycroft (a representative of the deep forces of the British government): a military analyst has disappeared mysteriously, and the data left behind points to a covered-up war crime in Afghanistan. The only key to deciphering the clue is actually closely related to John Watson's battlefield trauma seven years ago. As the investigation deepened, they discovered that the disappearance was just the tip of the iceberg. Behind the scenes is a systematic project codenamed "Undercurrent" - the military, intelligence agencies, and political and business giants work together to cover up war crimes and eliminate those who know the truth. John's late comrade David Russell was an early victim of the "undercurrent".
